가축 유래 staphylococcus aureus의 enterotoxin 산생과 plasmid profile에 관한 연구 II. 분리균주의 enterotoxin 산생

Enterotoxin Production and Plasmid Profiles of Staphylococcus aureus Isolated from Domestic Animals II. Enterotoxin Production of Isolates

The present study was conducted to investigate the enterotoxin types of Staphylococcus aureus isolated from bulk milk, Korean native cattle, pigs and poultry meat. Enterotoxins were produced by 88.0% of the organisms isolated from bulk milk, 76.2% from cattle, 64.7% from pigs and 22.5% from poultry meat. Enterotoxin type C and D were most common, being 42.0% and 12.8%, respectively. Enterotoxins were produced by all the strains of coagulase types Ⅱ, Ⅲ, Ⅳ and Ⅴ, 94.4% of type Ⅵ and 77.4% of type Ⅶ, while only 36.8% of the mixed type ⅡㆍⅢ produced enterotoxins. Commonly, coagulase types Ⅳ, Ⅴ, Ⅵ and Ⅶ strins produced enterotoxin C, and coagulase typis Ⅱ and ㆍⅢ strains produced enterotoxin D.
